We have a deployment server in a separate domain. I wanted to know if the deployment server needs to be able to connect to the license server. Do i need to open port 8089 from the deployment to the license server or visa versa?
If you think you have security problems while opening port to another domain. You can request deployment server license from Splunk support.
Of course, yes. Otherwise you will loose web authentication and deployment server functionality after your Splunk Enterprise trail is over.
